Spot

Spot ("Single Point Of Truth") is a concise, developer-friendly way to describe your API contract.

Leveraging the TypeScript syntax, it lets you describe your API and generate any other API contract formats you need (OpenAPI, Swagger, JSON Schema, Pact, API Blueprint), client SDKs (TypeScript, Swift, Kotlin) or even server boilerplate (e.g. Express).

You don't need to use TypeScript in your codebase to benefit from using Spot.

Example of an API definition file api.ts which defines a single POST endpoint to create a user:

import { api, endpoint, request } from "@zenclabs/spot";

@api()
class Api {
  @endpoint({
    method: "POST",
    path: "/users"
  })
  createUser(@request req: CreateUserRequest): CreateUserResponse {
    throw "contract";
  }
}

interface CreateUserRequest {
  firstName: string;
  lastName: string;
}

interface CreateUserResponse {
  success: boolean;
}

You can pass the definition above to a generator by simply running:

npx @zenclabs/spot generate --api api.ts

This is work in progress as of 14 Nov 2018:

• Functional TypeScript DSL
• Support for multiple files (using import statements)
• OpenAPI 3 generator
• OpenAPI 2 generator
• JSON Schema generator
• Pact generator
• API Blueprint generator
• TypeScript axios-based client generator
• TypeScript express-based server boilerplate generator

• Usage
• Commands

Usage

To get started and set up an API declaration in the current directory, run:

npx @zenclabs/spot init

You can then run a generator with:

npx @zenclabs/spot generate --api api.ts

Commands

• spot generate
• spot help [COMMAND]
• spot init

spot generate

Runs a generator on an API. Used to produce client libraries, server boilerplates and well-known API contract formats such as OpenAPI.

USAGE
  $ spot generate

OPTIONS
  -a, --api=api              (required) Path to a TypeScript API definition
  -g, --generator=generator  Generator to run
  -h, --help                 show CLI help
  -l, --language=language    Language to generate
  -o, --out=out              Directory in which to output generated files

EXAMPLE
  $ api generate --language typescript --generator axios-client --out src/
